Timeline of HAL Tejas
From Wikipedia, the free encyclopedia
- Indian government accepted the recommendation by its Aeronautics Committee that Hindustan Aeronautics Limited (HAL) should design and develop an advanced technology fighter aircraft around a proven engine
- HAL completed design studies in 1975, but the project fell through due to inability to procure the selected "proven engine" from a foreign manufacturer and unfulfilled IAF requirements.
- DRDO obtained permission to initiate a programme to design and develop a Light Combat Aircraft
- Government of India set up Aeronautical Development Agency (ADA) in 1984 as the nodal agency for managing and developing the LCA.
- IAF submits Air Staff Requirements (ASR) for LCA in October 1985. This was initiated by the then Air Chief Marshal Idris Hassan Latif.
- Government allocates 575 crores for the LCA programme.
- Programme to develop an indigenous powerplant (engine) was launched at GTRE.
- Project definition commenced in October 1987 with French Dassault Aviation as consultants.
- Project definition completed in September 1988.
- Government review committee expresses confidence in LCA programme. It was decided that the programme will be carried out in two phases.
- Design of LCA was finalised as a small delta winged relaxed static stability aircraft.
- Phase 1 of the development was commenced to create the proof of concept system. Financial problems within India prevented full scale operations from starting.
- Full funding started from April 1993 full-scale development work for phase 1 started in June.
- First technology demonstrator, TD-1, rolled out on 17 November 1995 and was followed by TD-2 in 1998. However, technical problems in flight control systems and structural deficiencies plagued the prototypes and they remained grounded.
- Multi-Mode Radar (MMR) for LCA design work started at HAL’s Hyderabad division and the LRDE.
- 4 May - LCA’s maiden flight successfully completed by Technology Demonstrator TD-1, on 2001. Prime minister Atal Bihari Vajpayee renames LCA as Tejas.
- Development assistance sought from Snecma on the Kaveri engine.
- 6 June - TD-2 makes a successful maiden flight.
- MMR system was reported to be not working as per the criteria laid down in requirements.
- 25 November - PV-1 makes a successful maiden flight.
- 1 December - PV-2 makes a successful maiden flight.
- 13 May - The PV-2 went supersonic for the first time
- 14 May - The PV-2 went supersonic again, but this time in a weaponised state (i.e., carrying weapons such as missiles and an internal gun).
- 1 December - The PV-3 flew for the first time for 27 minutes at an altitude of 2.5 km and at a speed of Mach 0.8. The PV-3 was equipped with a more advanced pilot interface, refined avionics and higher control law capabilities compared with the previous versions.
- 25 April - The first Limited Series Production LCA (LSP-1) made its first flight and it reached a speed of Mach 1.1.
- PV-2 and PV-3 underwent sea-level trials at INS Rajali Naval Air Station, Arakkonam to study the effects of flying at sea-level, as all earlier trials have been conducted at Bangalore which is 3,000 feet (910 m) above sea-level. The reliability of the LCA systems under the hot and humid conditions, as well as low level flight characteristics was tested. It is due to this intense flight testing schedule that the LCA was not able to fly at the Paris air show-2007, as was originally planned.
- 7 September - Tejas Prototype Vehicle (PV-1) made a successful maiden flight with two 800 litre drop tanks.
- 25 October - Tejas PV-1 fired a Vympel R-73 missile for first time. The trials were conducted off the Goa coast at INS Hansa Naval Air Station.
- 11 December - LITENING targeting pod was successfully tested on Tejas PV-2.
- 7 February - Tejas Prototype Vehicle (PV-1) made a successful flight powered by fuel from two 800 litre drop tanks. It made a one hour and 24 minute long sortie. On internal fuel LCA can perform a 40-minute sortie.
- April - First Flight with HMDS
- LCA Tejas prototypes PV-2 & PV-3 underwent hot weather flight trials at Air Force Station, Nagpur from 28 May 2008 to 4 June 2008. The trials were declared successful.
- 16 June - Tejas second Limited Series Production LCA (LSP-2) made its first flight and it reached a speed of Mach 1.1.
- 7 November - LCA Prototype Vehicle-3 made first successful night flight.
- 13 December - PV-3 and LSP-2 completed the high altitude trials at the Leh air base.
- 22 January - Tejas completed 1000 flights.
- February - the live bombs test were successfully carried out.
- October - PV-3 and LSP-2 completed visual target elimination and air-to-ground weapons delivery trials.
- 26 November - Two seater (Trainer) version of Tejas(PV-5) made its maiden flight on 26 Nov 09.
- 7 December - Tejas passed flight flutter test diving from an altitude of four kilometers to almost sea level at 900 feet (270 m). Tejas recorded a speed over 1350 km/h. These tests were conducted at INS Hansa, Goa.
- 15 December - Indian government sanctioned Rs 8,000 crores to begin production of the fighter jet for the Indian Air Force and Indian Navy.
- 23 April - LCA Tejas LSP-3 Makes Maiden Flight. LSP-3 is almost the final configuration including the new air-data computers, Hybrid Multi Mode Radar, new communication and navigation equipment and radar warning receiver. With this the LCA programme has completed 1350 test flights logging about 800 flying hours.
- 2 June - LCA Tejas LSP-4 Makes Maiden Flight. The flight marks the first time for a Tejas aircraft flying in the configuration that will be finally delivered to the Indian Air Force. In addition to the Hybrid MMR, the aircraft also flew with a functioning Countermeasure Dispensing System 
- 19 November - LCA Tejas LSP-5 Makes Maiden Flight. Goes supersonic in first flight.
- 10 January - Certification for the Release to Services with assured safety and specified performance for IOC.
- 26 January - LCA Tejas participates in the 26 January Republic Day Celebrations by being paraded at New Delhi.
- September - LCA Tejas undergoes bombing runs at Pokhran Test Range.
- 9 March - LCA Tejas LSP-7 Makes Maiden Flight

- 27 June - HAL Tejas (LSP 2, 3 and 5) completed precision bombing runs in the desert of Rajasthan, for the second time.
- 31 March 2013 - LSP 8 had a successful maiden test flight at Bangalore.
- 28 Sep 2013 - The Light Combat Aircraft (LCA) Tejas successfully completed the maiden engine relight test on Friday—a critical parameter the programme needs to achieve for the Initial Operational Clearance 2 (IOC-2). The Limited Series Production (LSP-7) aircraft from the Tejas flight-line, piloted by Gp Capt R R Tyagi, underwent the engine relight test at 1 pm. The LSP-7 was chased by a Hawk aircraft.
- 20 December 2013 - LCA successfully achieves IOC-2.
- 28 May 2014 - LSPs 3, 5 and 7 successfully complete advanced weapons trials.
